Some more new bioactive fluorine heterocyclic systems containing sulfur and nitrogen as five-membered rings: pyrazoline, imidazole, imidazolopyrimidine, thiazolidinone and 1,2,4-triazole derivatives (3-13) have been synthetically derived from the interaction of sulfa drugs with fluorine aromatic aldehyde and/or hexa fluoroacetic anhydride followed by heterocyclization reactions. Former structures of the targets have been deduced upon the help of elemental and spectral data.. Compounds 7a-f, 10c and 13 could be used as photochemical probe agents for inhibition of Vitiligo diseases, in compare with Nystatin and Nalidixic acid.
A heterocyclic, sp(3)-rich chemical scaffold was synthesised in just 6 steps via a highly regio- and diastereo-selective tandem nitrone formation/intramolecular nitrone-alkene [3+2] cycloaddition reaction. A library of 543 lead-like compounds based on the scaffold core has been produced.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
